v0.53.2

Patch Changes

• #4152 0c0462d Thanks @gabrielhl! - Reserve height as well as width in .ToggleSwitch-statusIcon so the switch doesn't jump when the loading spinner is shown

v0.53.1

Patch Changes

• #4133 0098814 Thanks @jonrohan! - Downgrade @oddbird/popover-polyfill to ^0.5.2 and pin it via Dependabot ignore so it won't get bumped again.

v0.53.0

Minor Changes

• #4110 bf92d87 Thanks @dylanatsmith! - Blankslate: The heading and body text now use the smaller compact sizes by default, and the redundant responsive @container block has been removed since the compact typography it produced is now the default

Patch Changes

• #3696 8b8d542 Thanks @myabc! - Fix incorrect label for attribute value when scope_id_to_model: false

• #4113 7c52375 Thanks @liuliu-dev! - Reject javascript: and vbscript: URI schemes in href (defense in depth). When a component (e.g. Primer::Beta::Label, Primer::Beta::Button, Primer::Beta::Link) is rendered as an anchor with an unsafe href, the value is now rejected — raising in non-production environments and silently dropped (rendered as an anchor with no href) in production.

• #4107 222a846 Thanks @dylanatsmith! - Fix ToggleSwitch knob spacing and border-radius to match primer/react

Patch Changes

• #4095 6733f3c Thanks @copilot-swe-agent! - Improve CSS style-recalc performance by removing selectors with universal subjects and expanding merged :is() selector lists so the browser can fast-reject them.
